I was just wondering if I needed to go get checked out about this. I was at my Nana's, she's diabetic, not blood related, she pricked my finger for curiosity and it was 4.7. I just had some dinner: pork chops, potatoes, asparagus, salad and a glass of wine. She said it was low, that it should be higher or around 5.4. Is this normal for me? I'm 5'1, 20yrs, f, between 110-115lbs. It would be great to know asap, thanks.

I wouldn't lose any sleep over it, but there's no harm in going and getting yourself checked out!
